The historical material is fascinating. I was particularly struck by the 13th century Ikh Zasag Law of the Great Mongol Empire: "In case a person arrives drunk at a workplace, first time impose a fine of a weapon he’s carrying with himself, second time impose the fine of a horse he’s riding, third time cut off an extremity of the body. If a fourth time, expel him out of the territory." I was also impressed by the account of Chinggis Khaan’s son, Uguude who responded to a strict observance of only three cups of alcohol per day by the simple expedient of creating a giant cup. According to the Secret History of the Mongols, he subsequently died of an alcohol related disease. A lesson for emperors everywhere.
